Swift Double isEqual()

// check if 10 is equal to 10 or not
var result = 10.isEqual(to: 10)

print(result)

// Output: true

isEqual() Syntax

The syntax of the isEqual() method is:

num.isEqual(to: otherNumber)

Here, num is a number.

isEqual() Parameters

The isEqual() method takes one parameter

• otherNumber - the value to test

isEqual() Return Values

The isEqual() method returns boolean value

• true - if num is equal to otherNumber
• false - if num is not equal to otherNumber

Example 1: Swift Double isEqual()

// check if 4 is equal to 2 or not
var result1 = 4.isEqual(to: 2)
print(result1)

// check if 2.0 is equal to 2 or not
var result2 = 2.0.isEqual(to: 2)
print(result2)

Output

false
true

Here, since 4 is not equal to 2, the isEqual() method returns false. However, 2.0 is equal to 2, the method returns true.

Example 2: Using if…else With isEqual()

// check if 88 is equal to 88.2 or not 
if 88.isEqual(to: 88.2) {
  print("The condition is true")
}

else {
  print("The condition is false")
}

Output

 
The condition is false

Here, since 88 is not equal to 88.2, the condition is false so the code inside the else block is executed.
